I believe in almost no predictions that assert a change from the existing regime. Regime shifts of this scale (a stop to equity growth) are extremely rare. But nobody publishes papers on why the existing status quo will continue. The show will go on, technology will be deflationary, which will support interest rate drops. Inflation will get sucked out of the economy, and life will go on.

Anyone that ever acted on advice like in this paper lost insane amounts of money.
